Abstract
Description
Die Erfindung betrifft einen Kraftstofffilter mit integrierter Wasserabscheidung zum Filtern des Kraftstoffs einer Brennkraftmaschine, mit einem Filtereinsatz in den eine Kraftstoffeingangsleitung mündet und mit einer Kraftstoffausgangsleitung in Strömungsrichtung hinter dem Filtereinsatz sowie mit einem geodätisch unterhalb des Filtereinsatzes angeordneten Wasserauffangbehälter.The The invention relates to a fuel filter with integrated water separation for filtering the fuel of an internal combustion engine, with a Filter insert into which a fuel inlet line opens and with a fuel exit line in the flow direction behind the filter element as well as with a geodesic arranged below the filter insert water collecting container.
Nachteilig an Kraftstofffiltern mit integrierter Wasserabscheidung ist, dass bei einem zu hohen Wasserstand im Wasserauffangbehälter als Folge von unterlassener Wartung bzw. unterlassener Entleerung der abgeschiedenen Wassermenge, eine weitere Abscheidung infolge des bis in den Filtereinsatz aufgestauten Wassers nicht mehr erfolgt und somit mit Wasser versetzter Kraftstoff in das Einspritzsystem der Brennkraftmaschine gelangt und dort zu Kavitationsschäden führt.adversely On fuel filters with integrated water separation is that at too high a water level in the water container as Consequence of omitted maintenance or omitted emptying of separated amount of water, another deposition due to the no longer takes place in the filter insert dammed water and thus water added fuel into the injection system the internal combustion engine passes and there leads to cavitation damage.
Zur
Vermeidung solcher Kavitationsschäden schlägt die
Der Erfindung liegt die Aufgabe zu Grunde, einen Kraftstofffilter mit integrierter Wasserabscheidung nach dem Oberbegriff des Anspruchs 1 so zu verbessern, dass die Betriebssicherheit der Brennkraftmaschine betreffend Kavitationsschäden am Einspritzsystem zu erhöhen.Of the Invention is based on the object, a fuel filter with integrated water separation according to the preamble of the claim 1 so as to improve the operational safety of the internal combustion engine concerning cavitation damage to increase the injection system.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention this Problem solved by the features of claim 1.
Dadurch, dass in der Kraftstoffausgangsleitung ein Sperrventil angeordnet ist, welches bei einem hohen Wasserstand im Wasserauffangbehälter den Durchsatz durch die Kraftstoffausgangsleitung bis auf einen Mindestdurchsatz verringert, ist der Betreiber gezwungen das abgeschiedene Wasser abzulassen, da die Brennkraftmaschine nur noch mit einer reduzierten Leistung betreibbar ist. Der Mindestdurchsatz durch das Sperrventil sollte zumindest der erforderlichen Leerlaufmenge der Brennkraftmaschine entsprechen, so dass ein Sicherheitsbetrieb möglich ist, um z.B. einer Gefahrensituation zu entgehen. Dadurch, dass nunmehr gezwungenermaßen das abgeschiedene Wasser abgelassen wird, ist das Auftreten von Kavitationsschäden infolge von Wassereintritt am Einspritzsystem ausgeschlossen.Thereby, arranged in the fuel outlet line, a check valve is, which at a high water level in the water collecting the Throughput through the fuel output line to a minimum throughput reduced, the operator is forced the separated water let off, because the internal combustion engine only with a reduced Performance is operable. The minimum flow rate through the check valve should at least the required idling amount of the internal combustion engine so that a safety operation is possible, e.g. a dangerous situation to escape. Thereby, that now forced the separated water is discharged, the occurrence of cavitation damage due excluded from entry of water to the injection system.
In einer erfindungsgemäßen Ausführungsform ist das Sperrventil ein Magnetventil, welches im bestromten Zustand die Kraftstoffausgangsleitung geöffnet hält und im stromlosen Zustand die Kraftstoffausgangsleitung verschließt.In an embodiment of the invention the check valve is a solenoid valve, which is in the energized state the fuel outlet line opened stops and in the de-energized state, the fuel outlet line closes.
Hierbei ist das Magnetventil bevorzugt durch einen Wassersensor gesteuert, wobei bei niedrigem Wasserstand im Wasserauffangbehälter der Wassersensor das Magnetventil bestromt und bei hohem Wasserstand oder bei nicht arbeitendem Wassersensor das Magnetventil stromlos hält.in this connection the solenoid valve is preferably controlled by a water sensor, wherein at low water level in the water catchment of the Water sensor energized the solenoid valve and high water level or if the water sensor is not working, the solenoid valve is de-energized holds.
Damit bei einem Ausfall des Wassersensors das Magnetventil schließt, weist der auslenkende Teil des Magnetventils in einer bevorzugten Ausführungsform einen Sperrkolben auf, der von einer Druckfeder in eine die Kraftstoffausgangsleitung verschließende Sperrstellung kraftbeaufschlagt ist.In order to in case of failure of the water sensor, the solenoid valve closes, points the deflecting part of the solenoid valve in a preferred embodiment a locking piston, which from a compression spring in a fuel outlet line closes Locking position is subjected to force.
In einer alternativen Ausführungsform weist das Sperrventil einen Einsatz auf, der sich bei Wasserkontakt auflöst und dadurch ein vorgespanntes mechanisches Schließventil freigibt, welches die Kraftstoffausgangsleitung anschließend verschließt.In an alternative embodiment the check valve has an insert which contacts when in contact with water dissolves and thereby a biased mechanical closing valve releases, which then closes the fuel outlet line.
Vorteilhafterweise ist das Schließventil ein über eine Druckfeder in Schließstellung vorgespannter Kolben, der mit dem Einsatz im trockenen Zustand fest verbunden ist und bei Auflösung des Einsatzes dieser Verbund gelöst ist.advantageously, is the closing valve one over a compression spring in the closed position preloaded piston, which stuck with the insert in the dry state is connected and at resolution the use of this composite solved is.
Zweckmäßigerweise ist der Einsatz eine Patrone, die konzentrisch vom Filtereinsatz umgeben ist.Conveniently, The insert is a cartridge concentric with the filter cartridge is surrounded.
In einer weiteren Ausführungsform ist das Sperrventil ein kraftstoffdurchlässiger Einsatz, der bei Wasserkontakt quillt und dadurch die Kraftstoffausgangsleitung verschließt.In a further embodiment the check valve is a fuel-permeable insert that contacts when in contact with water swells and thereby closes the fuel outlet line.
Bei einer Entfernung des Einsatzes schließt das Schließventil oder das Sperrventil die Kraftstoffausgangsleitung automatisch, wodurch auch bei einer Manipulation am Kraftstofffilter bei einem überhöhten Wasserstand nur ein leistungsreduzierter Betrieb der Brennkraftmaschine möglich ist.at a removal of the insert closes the closing valve or the check valve the fuel output line automatically, whereby even with a manipulation of the fuel filter at an excessive water level only a reduced-power operation of the internal combustion engine is possible.
Zur Aufrechterhaltung eines Leerlaufbetriebs der Brennkraftmaschine auch bei geschlossener Kraftstoffausgangsleitung bzw. zu hohem Wasserstand im Kraftstofffilter weist das Sperrventil bevorzugt eine als Drossel wirkende Bypassleitung auf.to Maintaining an idling operation of the internal combustion engine even with closed fuel outlet line or too high water level in the fuel filter, the check valve preferably has a throttle acting bypass line.
Bevorzugt ist die Brennkraftmaschine eine selbstzündende Brennkraftmaschine (Dieselmotor.)Prefers the internal combustion engine is a self-igniting internal combustion engine (diesel engine.)
